managing /var/apache/access_log and error_log

My /var/apache/access_log and error_log are getting to big. I want to just keep the last 500 lines of each. Can I use the tail -500 comand and copy to another file and remove the original and rename the file witrh the last 500 lines to the original and can I do this while the system is running?

Or use cron to run a script to rotate the logs:

yuzh.

In your rotation script, I  would change

cp -p access_log access_log.${TODAY}
cp -p error_log error_log.${TODAY}
cat /dev/null > access_log
cat /dev/null > error_log

to

mv access_log access_log.${TODAY}
mv error_log error_log.${TODAY}

As mv is an atomic process and will be much quicker than copying the logs.  Additionally, if your logs are big and your freespace is low, you may run into space issues.

Tintin,
     thanks for the suggestion, after "mv", you need to "re-create" the log files
and set the correct file permissions (use "touch + chmod").

Easiest way to recreate those log files after a mv is: apachectl graceful

It'll recreate everything for you with the default permissions- much less room for script error :)

If you traffic is high enough, this could be done every 10-15 min.
